Safety and Reliability in a Compact Metering Pump | Primeroy K (PKG)

The PRIMEROY K (PKG) compact metering pump guarantees safe, precise, and reliable dosing of any fluids, powered by its exclusive patented GSD design.

  • Material (liquid end): 316L S.S. / PVC
  • Pressure max: 536 psi / 37 bar (metallic liquid end); 150 psi / 10 bar (plastic liquid end)
  • Flow max: 660 gph / 2500 lph

Multiplexing capabilities

  • Flow variation control: Manual/Remote
  • Certifications: API 675, EC, ATEX, IECEX

API-Compliant, Industrial-Grade Design

Fully compliant with API 675 and major global standards (ATEX, IECEx, NACE), ensuring safe and reliable operation in critical industrial environments worldwide.

Precise Flow Control & Adjustability

Micrometric stroke adjustment enables accurate, repeatable dosing from 0–100%, even during operation, ensuring process stability and flexibility.

Advanced PTFE Diaphragm Safety

Triple hydraulic safety system with PTFE diaphragm design prevents leaks, protects against overpressure, and ensures reliable operation in demanding applications.                                                                                                                                                                                      

Built-In Monitoring & Diagnostics

Visual IMI system detects overpressure, cavitation, and dosing instability, helping operators quickly identify issues and maintain accurate performance.

Modular & Configurable Design

Highly adaptable with multiple liquid ends, valves, and control options, allowing precise configuration for specific process requirements.

Long-Life Performance in Extreme Conditions

Robust construction, oil-bath lubrication, and high-quality materials ensure over 20,000 hours of leak-free operation, even in offshore, corrosive, or harsh environments.

Simplex PRIMEROY® PKG Pump Performance

Model PKG provides accurate dosing of a broad spectrum of fluids used in many industrial processes thanks to their modular design which offers several types of liquid ends, capacity control options and other configuration options enabling them to meet the specific requirements ofyour process application.

The main benefits of the PKG are its special compact design, the Global Security Device (GSD) and the Installation Monitoring Indicator (IMI). The model PKG is designed for high flow rates (2500 L/h – 659 GHP for a simplex configuration) and mid pressure applications (37 bar – 536 psi).
